> FindBugs-3.0.1 ([http://findbugs.sourceforge.net/]) reported two
> WMI_WRONG_MAP_ITERATOR warnings on master:
> {code:java}
> M P WMI: org.apache.flink.runtime.state.ttl.TtlMapState.putAll(Map) makes
> inefficient use of keySet iterator instead of entrySet iterator At
> TtlMapState.java:[line 72]
> M P WMI: org.apache.flink.addons.hbase.HBaseTableSource.projectFields(int[])
> makes inefficient use of keySet iterator instead of entrySet iterator At
> HBaseTableSource.java:[line 19]
> {code}
> The description of the bug is as follows:
> {quote}*WMI: Inefficient use of keySet iterator instead of entrySet iterator
> (WMI_WRONG_MAP_ITERATOR)*
> This method accesses the value of a Map entry, using a key that was retrieved
> from a keySet iterator. It is more efficient to use an iterator on the
> entrySet of the map, to avoid the Map.get(key) lookup.
